椎弓根钉系统内固定并椎管前方撬拨治疗胸腰椎爆裂骨折疗效分析

TREATMENT OF THORACOLUMBAR BURST FRACTURE WITH PEDICLE OF VERTEBRAL ARCH SCREW AND WITH KNOCKING THE FRACTURE SEGMENT INTRODUCING INTO THE SPINAL CANAL

目的探讨应用椎弓根钉系统内固定合并椎管前方撬拨方法治疗胸腰椎爆裂骨折的疗效.方法收治T12～L4胸腰椎爆裂性骨折患者43例,应用椎弓根钉复位固定后,行伤椎椎管前方撬拨,骨折复位.结果 39例获得随访,随访时间6～28个月,平均15.5个月.38例脊髓不完全性损伤患者中,36例术后有1～3级以上的神经功能恢复,无1例出现神经功能障碍加重.结论椎弓根钉系统内固定合并椎管前方撬拨方法治疗胸腰椎爆裂骨折,能有效恢复脊柱的序列,进行椎管前方减压,重建脊柱的稳定性.

Objective To research the clinical outcome and efficacy with pedicle of vertebral arch screw and with knocking the fracture segment introducing into the spinal canal in treatment of thoracolumbar burst fracture. Methods 43 eases of thoracolumbar burst fracture from T12 to L4 were selected, treated with pedicle of vertebral arch screw and with knocking the fracture segment introducing into the spinal canal. Results 39 eases were followed up from 6 to 28 months, mean 15.5 months. For the patients with incomplete spinal cord injury, the Frankel was improved for 1 to 3 grades in 36 eases. Conclusion The operation can significantly recover the spinal rank and reconstruct the spinal stability and anteriorly decompress the spinal canal.
